1. 描写海洋被污染的段落
具体如下：
1、垃圾污染
工业冷却水和工程残土、垃圾及疏浚泥等。前者入海后能提高局部海区的水温，使溶解氧的含量降低 ，影响生物的新陈代谢，甚至使生物群落发生改变；后者可破坏海滨环境和海洋生物的栖息环境。
2、噪声污染
利用天然声纳进行导航和捕猎，让无脊椎动物深受其害。勘探船产生的声音污染对头足类动物以及其他海洋动物的生存造成不利影响。
3、过度捕捞
人类的捕鱼活动导致海洋中生存的某种鱼类种群不足以繁殖并补充种群数量。现代渔业捕获的海洋生物已经超过生态系统能够平衡弥补的数量，结果使整个海洋系统生态退化。
4、冰川融化
由于冰盖的融化，奇特的低盐度海水正在慢慢的消失，截止到2002年， 96%的低盐度栖居环境已经消失殆尽。大部分以冰川径流作为供水源的地区将会发生严重的缺水危机。
5、石油泄漏污染
石油污染在海洋表面形成面积广大的油膜，阻止空气中的氧气向海水中溶解，同时石油的分解也消耗水中的溶解氧，造成海水缺氧，对海洋生物产生危害，并祸及海鸟和人类。
2. 海水被污染的句子
1、滔滔白浪从天际滚滚而来，银白皎亮的波涛推涌追逐，渐渐由远而近，越近越高，越高越响，宛如千军万马挟着雷鸣一般的轰然巨响奔腾而至。
2、一层层的浪涛向远处扩展延伸，慢慢平息下去，像是喘一口气似的，留下一片转瞬即逝的泡沫，还有摇晃着的海藻的霉腥味。
3、爱心是暗夜大海中灯塔上的一盏明灯，使惊涛骇浪中的水手们看到重生希望。
4、汹涌澎湃的浪花不断地拍打着海岸。
5、大海有时像一头咆哮的猛虎，汹涌澎湃，掀起阵阵狂澜，汹猛的海浪不时拍打着礁石，它，溅起一片片晶莹的浪珠；有时又像一位温柔的妈妈，让海浪欢快的跳跃。
6、平静的海面上忽然狂风大作，大海变的汹涌澎湃起来，海水以排山倒海之势压过来，吓的新船员们心惊肉跳。
3. 描写海洋被污染的段落摘抄
来自长江和省内6大水系所携带的大量工农业废水和生活污水排入海中，使我省87％的近岸海域受到不同程度的污染，基本已无I类海水，沿海特别是河口海水中无机氮和无机磷严重超标，海水中磷酸盐合量在沿海省、自治区和直辖市中排居首位。
近岸海底沉积物中氮、磷超标严重，成为海水二次污染的潜在危害源。另外，个别海域（如杭州湾和舟山海域）船舶排污及碰撞漏油，海上石油开采溢油等加剧了近岸海域的污染，有机污染和重金属也对海水水质产生明显的影响。
海洋灾害频繁——每年发生大小赤潮近20次
我省是风暴潮、赤潮等海洋灾害最为严重的省份之一。每年因台风给我省海洋渔业造成的直接经济损失在数十亿元以上。由于海水水质下降和富营养化，导致赤潮灾害发生的频率逐年上升，给我省的海洋经济带来巨大的损失，近年来，每年发生的大小赤潮灾害近20次，年直接经济损失达数亿元。
围海造地——许多珍稀濒危野生生物绝迹，破坏生态
我省沿海滩涂资源359．04万亩，主要分布在钱塘江和杭州湾两岸，以及各海湾。由于不合理的围海造地，使沿海自然滩涂湿地面积缩减，不仅破坏了多种鸟类的栖息地，也使重要的经济鱼、虾、蟹和贝类生息、繁衍场所消失，许多珍稀濒危野生生物绝迹，而且大大降低了滩涂湿地调节气候、储水分洪、抵御风暴潮、净化地表径流及护岸保田等的能力，同时改变了海区的水动力方向，加速了航道和港口的淤积。
海洋食物链已经遭到严重破坏——经济鱼类资源大幅度降低
随着海洋开发话动的增多，海洋生态环境遭受破坏，使生物多样性衰减，某些生物种类已近绝迹，传统的经济鱼类资源大幅度降低，再也形不成渔汛，海洋食物链已经遭到严重破坏。东海生态系统中的主要经济物种严重衰竭，整体结构发生显著变异，系统内部自我调节的能力受到严重损害。
请勿将废水和生活垃圾直接排入海中
造成海水如此恶劣的污染源主要有陆上和海上两大类。陆上污染源主要是工业污水、居民的生活废水以及农田中使用的农药通过河流流入大海，沿海企业和居民直接将污水和废水排入海中。海上的污染源主要有船舶上和港口的油污和生活废水，养殖场、海洋工程、海岸工程产生的污染。
为了使我们的海域不再受污染，省有关部门已经颁布了一系列的政策法规对海域污染进行了治理。同时也提醒沿海的居民不要将废水和生活垃圾直接排入海中，出海的渔民应该把该回收的都要回收，而不要一丢完事。
4. 描写海洋被污染的段落200字
是石油，进入海洋的石油在海浪、海流作用下扩散形成很薄的油膜覆盖在海洋表面，不仅隔绝了大气与水的气体交换，也由于自身的生物分解和氧化作用消耗掉海水中含有氧气，造成海水中氧气含量的大幅度下降
5. 描写海洋被污染的句子
海洋污染物依其海洋污染来源、性质和毒性，可分为以下几类：
①石油及其产品(见海洋石油污染)。
②金属和酸、碱。包括铬、锰、铁、铜、锌、银、镉 、锑 、汞 、铅等金属，磷、砷等非金属，以及酸和碱等。它们直接危害海洋生物的生存和影响其利用价值。
③农药。主要由径流带入海洋。对海洋生物有危害。
④放射性物质。主要来自核爆炸、核工业或核舰艇的排污。
⑤热污染和固体废物。主要包括工业冷却水和工程残土、垃圾及疏浚泥等。前者入海后能提高局部海区的水温，使溶解氧的含量降低 ，影响生物的新陈代谢，甚至使生物群落发生改变;后者可破坏海滨环境和海洋生物的栖息环境。
⑥有机废液和生活污水。由径流带入海洋。极严重的可形成赤潮。
6. 描写海洋被污染的段落有哪些
污水给鱼儿带来的只有死亡，如果人们吃了被污染的海里的鱼，大多数会生病的就海洋污染而言，是个大问题呀！海洋生物物种一旦遭难，生态就会失去平衡，也许会就此产生新物种来适应这种恶劣环境也说不定。但最大的可能就是愈演愈烈，最终地球将会成为一颗“死亡星球”。到时我们就惨了，还是现在好好保护吧。
7. 描写海洋被污染的简短优美句
对海洋生态系统的破坏主要表现在：（
1）渔业捕捞过度和海水养殖管理不善。海洋捕捞产量的迅速增加是机动渔船大量增加的结果。但是，逐年增长的捕捞力量主要集中在近海渔场，造成近海渔业资源开发利用过度。过度的开发利用导致优质鱼类资源严重衰退，渔获物中主要经济鱼类所占比例逐年减少，个体也趋向小型化、低龄化，低质小杂鱼所占比例逐年增加。
有些地区的海水养殖业管理不善，出现了污染海洋生态环境的倾向，如养殖过程中产生的废水造成海水有机物污染和富营养化；大量采捕饵料生物，使部分滩涂贝类大量减少，破坏了正常的食物链；等等。
（2）滩涂围垦和填海造陆夺走了大片海洋生境。沿海滩涂大量围垦和人工填海造陆等，不仅使许多海洋动物失去了大面积的栖息地、产卵地、育苗场、索饵场

Pollution
Sea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.
I need to describe the problem. Our ship currently dumps all its rubbish into the sea.It's easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.
I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly. A case in point is that we should stop providing plastic bags.
We must act now before it is too late!
海洋污染英语作文二：Reduce Sea Pollution
Several problems are caused by the non-organic substance. We ought not to pour wastes into the ocean, because it not only pollutes the ocean, but also lead to a series of harmful consequence. First and foremost, the non-organnic things, for instance, plastic bags, may kill fish and whales. Second, fishes can't digest them. Finally, some of the rubbish is inherently toxic, they will posion marine life.
We must take actions to protect our whale from dying. One thing we should do is creating a better system of disposing of rubbish. Another effective solution is making ships environmentally friendly. Sypermarkets shall stop the giving of plastic bags.
As a captain of the ship, you should spare no efforts to think more helpful ideas and stop dumping rubbish from now on. We all need to raise awareness of these problems. It now becomes necessary that we must act now, before it is too late!
海洋污染英语作文三：Sea pollution
Between 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. Around 12% of the pollution is caused by maritime transport.
In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2003, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2006.
Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water...), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides...) and agricultural waste (fertilisers, pesticides...).
This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.
海洋污染英语作文四：Sea Pollution
Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.
The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the world's 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,Marine living resources are likely to cause more damage.
The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.
海洋污染英语作文五：Polluting the seas
The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.
In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.
As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

From the overall situation, wastewater emissions growth speed. Is expected in 2000 will reach 666 tons. City life sewage volume will continue to increase, in 2000 reached about 783 tons. The wastewater of low (estimated at 20% ~ 30%),most of untreated wastewater directly or indirectly discharged into the water body, the serious pollution of water resources. China's seven major river systems in nearly half of serious pollution, city section of river water qualitygenerally exceed the standard 86%. The polluted water, more serious is the Huaihe, Haihe, Liaohe, Songhua River, the downstream Yangtze River and the Pearl River Delta industries in developed region.
River city section of riverpollution, heavy on the river, north to south. In 1990, 94 river city section of evaluation, 65 are subject to different degrees of pollution, accounting for 69.1%, the main pollutants ammonia nitrogen, volatile phenol and oxygen consumption of organic matter. According to the survey, 700000000 peopledrinking water the Escherichi a coli exceed the standard, 164000000 people drink organic pollution of water, 35000000 people nitrate drinking water exceed the standard.
Huaihe is one of the most polluted rivers. Huaihe in the evaluation of the 2000kilometers of the river, 78.7% river does not meet the drinking water standard,the 79.7% section does not meet the standard of fishery water, 32% do not meet the standard of irrigation water. According to statistics, the national 3000 heavily polluting enterprises, enterprises of wastewater discharge of industrial pollution,Huaihe River Basin accounts for 160. A sewage units 1.55 182 towns within the basin, industrial wastewater emissions of 1610000000 cubic meters, 700000000 cubic meters of urban living water emissions. Huaihe sewage irrigation farmland,causing serious crop production; in 1989 the occasion of the Spring Festival, the sewage discharge upstream gate opening, the tap water in Huainan, Bengbu twocity is seriously polluted and not drinking, Huaihe basin, the public drinking watercrisis, people Voices of discontent.

9. 海边被污染的描写
黄昏，我觉得是一天中最美的时刻。黄昏的海边，更是美的了。
那沙滩上的贝壳，颜色 、形状都大不相同。有的贝壳是扇形的，说不定是有珍珠的呢；有的贝壳五角形，就像天上的小星星。夕阳照在贝壳上好像铺上了金莎，美极了。
大海把浪水推到金沙滩上，让它休息，别着凉。片刻，又把浪水带回自己身边，不可思议。海鸥在海上飞着，好像在说：“大海好美啊，好美啊！”当然，黄昏照在大海上，所以非常的美。一丝阳光照在海面上。金色的海面波光粼粼，简直是金子掉进了海里。那帆船慢慢地游过，也为大海增添了风景线。
夕阳中的晚霞，差不多都是金色的，也有一些是红的，都有绚丽，仿佛一个彩虹世界。
我喜欢黄昏的海边，它给我增添了乐趣！
